eeegioeu To all whom it may concern:

Be it known that 1, JAMES G. ALEXANDER, citizen of the United States of America, and resident of Ames, Story county, Iowa, have invented it new and useful Hoke, of which the following is a specification. V

The object of. this invention to provide improved means for collecting, conveying and delivering hay and bunclle grain,

A furtner object of thisinvontion is to rovide means for oscillating,- a relie i'eln tlve to the axes of supporting wheels by manual actuation in one direction and by travel draft in the opposite direction,

A further object of this invention is to increase the capacity of a rake in respect of or relative to its axis of oscillation.

A further object of this invention is to provide such connection between a rake end hi1 might t (heft (levices'that forward strain of the draft devices will tend to raise the rake from collecting to carrying position.

A further object of this invention is to provide means for balancing e. mice in can ing position on a truck.

My invention cons'sts in the consti'iu'ztion, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in Which Figure l is a plan of the rake, drewing and steering mechanism being omitted, the

In the construction of the rake shown the numeral 10 designates a beam or crossbar which may he of; any desired construction. A IRlifi he (ll 11 is arranged parallel with and spaee'l :rmn and. at the rem. of the beam 10. he teeth Ii, are arranged at and extend act" the locum or cross bav it. The mice teeth are lined intermediate of their ends to the beam 10 and are fixed at their rear ends to the rake head 11 anvl said t Ellll have approximately two-thirds of the length in.

A boom 5 lined at its to'rwarfii J-l'lll to a. portion cit l in v coinnion me siilcl'i as a central tooth or the antral portion of the beam 10 21ml extends l7 \\2lii'fll therefrom across the mice site end rear end porti on of the boom 30, the oppoportion of said lever extending within reach of the operator on the seat 29 and susceptible of manipulation by him, Any desired means may be employed for holding the lever 81 in any desired position and as such rneans are common and well known and form no part of my present in- .vention, they are not illustrated nor de scribed.

In the practical use of my invention the machine is advanced over the surface of a field containing hay, flax or the like 1n windrows orbundle grain'in bunches or shocks and in such advance the rake proper is in clined into the position shown by solid lines in Fig. 2,: by manipulation ofthe actuatingdevices 31. In such inclining of the rake teeth the boom 30 is raised at its rear end until the beveled forward end portions of the teeth are on or 'near to the surface of the ground, even to the extent of raising the rake head, beam and guard until the chains 24,-, 25 are slackened. This is to insure the forward end portions of the teeth entering beneath the substance to be received thereby. In the further advance of the rake the substance to be loaded is received on the rake teeth, said teeth passing beneath such sub- 3'5 10 is located approximately centrally un stance untilfurther progress in that direction is stopped by engagement of the guard 26 withthe substance and this operation is continued until a maximum load is received on the teeth and retained by the guard, and

at such time it will be found that the beam' der the load in respect of the weight of such load.

At such time as the maximum load is received the boom lis, released by reverse operation of the actuating-devices l and further advance of the machine through the pushing influence ofthe tongue 27 acting on the central portion of the beam 10, said beam being located centrally of the load,

the rake teeth, rake head and guard assuming the position shown in Figs. 1 and 3 and shown by dotted. lines in. Fig. 2, namely, the

The elements may manipulation of the by the automatic-normal tendency of the beam, teeth, rake head and guard to assume such position under the thrust of the tongue into delivery position,

previously described.

27. The machine is then' advanced to'tlie place of-deposit with the elements in carrying position and at such place of deposit the rakeproper is again tilted .th'rou'gh manipulation of the actuating devices 31 which delivery posi tion is identical with the'collecting position Then the apparatus is withdrawn from the load by reverse movement which efiects the withdrawal of the teeth from beneath theload.
